DEXTER, MICHIGAN NAILING Application filed July 8,

This invention relates generally to nailing machines and has for an object to provide a machine particularly useful in automobile u carriers such .as freight cars and the like for driving automatically and quickly into the floor of the carrier the nails or other securing means for the floor plates of hold-down devices used as anchorage means for the autolmobiles while in transit.

` Another object is to provide a machine that is constructed and arranged in such .a way that it may be conveniently and expeditiously used upon carrier flooring under automo biles or other obstacles for driving the nails 11.5r aforesaid into the flooring.

With the above and other objects in view, the invention consists of certain novel features of construction, combinations and ar urangements of parts that will be hereinafter `more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a fragmentary sectional view of a freight car and showing a machine emafbodying my invention in operative position upon the flooring beneath an automobile;

Figure 2 is a perspective view of the machine and of a floor plate upon the flooring of the freight car; Figure 3 is a top plan view of the machine; Figure 4 is a side elevation of the machine; Figure 5 is an end elevation of the machine;

Figure 6 is a vertical sectional view taken a5 on the line 6 6 of Figure 3;

Figure 7 is a cross sectional view taken on the line 7 7 of Fi ure 2.

Referring now to tie drawings, 1 is the flooring of a suitable carrier such as a Il@ freight car, 2 is an automobile on the flooring, 3 is a iioor plate of a hold-down or anchorage device for the automobile, 4 designates the nails extending through the floor plate into the flooring, and 5 is a machine 45 embodying my invention for driving the nails 4 into the flooring 1 to hold the plate 3.

As shown, the nailing machine 5 includes an upright substantially U-shape frame 6 ff" having the wheels 7 thereof resting on and MACHINE 1929. Serial No. 376,644.

movable over the flooring, a base 8 having one end secured to and projecting laterally from the base 9 of the frame 6 and having its other end resting upon and slidable over the flooring 1, a weight 10 of substantially rectangular configuration constituting a hammer, arms 11 and 12 terminally connected to opposite ends of said weight and to a shaft 13 carried by the arms 14 and 15 of the U- shape frame 6 at the upper end thereof, a cross bar 16 extending between and terminally secured to said arms 11 and 12 adjacent to the U-shape frame 6, a rocker 17 mounted upon the shaft 13 between the arms 14 and 15 of the frame 6 and having an arm 18 between and substantially parallel to the arms 11 and 12 secured to the cross bar 16 and projecting forwardly beyond the same, and actuating means for the weight 10 including a crank 19 engageable with the arm 18, a shaft 2O for the crank, an electric motor 21 having a shaft 22, gears 28, 24, and 26 connecting the shafts 22 and 20, and a coil spring 27 terminally connected to said base 8 and to an upstanding lug 28 on the arm 14.

Preferably a rod 30 is terminally connected to a lug 81 upon the weight 10 and to the lug 28 and serves to retain the weight 1() in proper position to engage the heads of nails to be driven thereby.

Thus with this construction the floor plate 8 may be positioned at the proper point upon the flooring beneath the automobile, and

nails such as 4 may be initially driven by any suitable means into the flooring. The nailing machine is then moved over the flooring to the proper position under the automobile, as illustrated in Figure 1, so that the weight 1() may be used to drive the nails home into the flooring. In this connection it will be noted that the crank 19 operated by the mo tor 21 merely raises the weight 10 relative to the nails and flooring, while the spring 27 simulates the action given to a hammer by ones arm and causes the weight 10 to move downwardly upon the nails with snap-like action. As a result of force imparted to the weight by the spring the nails are driven quickly by a succession of quick blows into the flooring. Moreover, a single nail or a plurality thereof may be driven by the weight into the flooring.

rIhus, from the foregoing description it will be readily apparent that I have provided a simple but very effective means for driving nails and the like and that it is capable of use in comparatively small places where it is impractical for nails to be driven home by hand. Moreover, its usefulness in driving a plurality of nails instead of only one and its ability to drive them automatically and faster enables a given job to be performed in less time and at a lower cost than heretofore.

What I claim as my invention is:

l. In a nailing machine, weight serving as a hammer, a rocker at a point remote to said weight, an arm projecting from said rocker, a shaft for said rocker, arms terminally connected to said weight and shaft, a connection between said rocker arm and one of said last mentioned arms, and actuating means for said weight including a rotary element engageable with the rocher arm, and a. yieldable element connected to said rocker.

2. In a nailing machine, a wheeled frame having a pair of upstanding arms, a shaft carried by said arms, a rocker carried by said shaft and having an arm, a weight substantially parallel to said wheeled frame, and a connection between said weight and rocher including arms connected to said weight and shaft, a base projecting from said Wheeled frame and disposed between the weight and wheeled frame and between the last men tioned arms, and actuating means for said weight including means carried by said base and enga geable with said rocker arm.

3. In a nailing machine, a wheeled f lame having a pair of upstanding arms, a shaft carried by said arms, a rocker carried by said shaft and having an arm, a weght substantially parallel to said Wheeled frame, and a connection between said weight and rocker including arms connected to said weight and shaft, a base projecting from said wheeled frame and disposed between the weight and wheeled frame and between the last mentioned arms, and actuating means for said weight including a crank engageable with said rocher arm, a motor on said base, and operative connections between said motor and crank also carried by said base.

Ll. In a machine of the class described, a wheeled frame, a rocker carried thereby and having an arm, a weight serving as a hammer, means for actuating said weight including means engageable with said roel-ter arm, and mea-ns for holdineV said weight in a predetermined position for engagement with nails and the like including` a connection between said weight and frame.

5. In a nailing machine, a weight serving as a hammer, a wheeled frame, a pivot shaft carried by said frame, a rocker on the pivot shaft having an arm projecting at substantially right angles to the shaft, a bar connected to and projecting laterally from said arm, an arm substantially parallel to the arm aforesaid terminally connected to said pivot shaft and weight and connected intermediate its ends to the bar aforesaid, and actuating means for theA weight including a movable part engageable with the rocker arm.

6. In a nailine machine, a wheeled frame having ground-engaging wheels, a groundengaging weight at a point remote with respect to said frame, a pivot shaft carried by said frame, an arm freely connected to said pivot shaft and weight, a rocker freely mounted on said pivot shaft and having an arm connected to the arm aforesaid, and actuating means for said weight including means engageable with said rocker arm.

7. In a nailing machine, a base, a rocher at one end of said base, a weight beyond the other end of said base and movable upwardly and downwardly respectively from and to the h crizontal plane of said base, actuating means for the rocher carried by said base, and a driving connection between said rocker and weight inovaale freely relative to said base.

8. In nailing machine, a base, a shaft at one end of said base, a weight beyond the other end of said base and movable upwardly and downwardly respectively from and to the horizontal plane of said base, a rocker en the, shaft and having an arm, actuating means for the rocker carried by the base and engageahle with the arm, and a driving connection between said rocker and weight including a part terminally connected to said weight and shaft and indirectly connected to said arm.
